I know right? Black applicants with high MCAT scores were rejected in favor of white applicants with low MCAT scores! Just unbelievable.

Unbelievable because it’s the opposite of what the link shows?

96% acceptance rate for black candidates with high MCAT scores, but a nonzero acceptance rate for white candidates with low scores.

Maybe there are other factors, and they're correlated with the buckets being used here?

It’s not the case that every single black applicant gets admitted before a single white/Asian applicant does. The point is that it’s much, much easier for a black applicant to get admitted.

A black applicant with GPA and MCAT scores in the lowest bucket still has a 56% chance of admission. That’s on par with an Asian applicant who has GPA and MCAT scores in the highest bucket.
